Elementary Principles of Chemical Processes

3. Benzene (C6H6) is converted to cyclohexane (C6H12) by direct reaction with H2. The fresh feed to the process is 260L/min of C6H6 plus 950L/min of H2 at 100C and 150kPa. The single-pass conversion of H2 in the reactor is 48% while the overall conversion of H2 in the process is 75%. The recycle stream contains 90%H2 and the remainder benzene (no cyclohexane). See the figure below. Figure 1: Schematic (a) Determine the molar flow rates of H2,C6H6 and C6H12 in the exiting product. (b) Determine the volumetric flow rates of the components in the product stream if it exits at 100kPa and 200C (c) Determine the molar flow rate of the recycle stream, and the volumetric flow rate if the recycle stream is at 100C and 100kPa
